Encrypt data

Understand data encryption for fields

  • Applies to the following fields: Single line, email, date, date-time, number, percent, decimal, and currency
  • Learn how to manage data encryption for fields

Data encryption is a widely used measure to protect data. Encryption At Rest (EAR) is a data protection measure that stores data in an encrypted format when it's at rest (not moving). You can enable EAR for the data stored in the fields of your Zoho Creator app by enabling the Encrypt data field property.

Refer to this page to learn about Zoho's security practices, policies, and infrastructure.

Before enabling data encryption

  • Encryption converts the data in a field to text. Therefore, to enable data encryption for a field, you will first need to remove its references from other components like lookup fields (in other forms), reports, and workflows. Zoho Creator will display a prompt containing all such references. Refer manage data encryption to learn more.
  • Enabling data encryption is not supported when the no duplicate values property is enabled for that field, and vice versa
  • Encrypting data requires time. We've estimated that it takes up to 30 seconds to encrypt the data in 100,000 records. However, while this happens, your users won't be able to access your app. For example, if you initiate data encryption for a field while a user is entering data in that form, they won't be able to submit the form. We recommend that you plan for this pause before you initiate data encryption for a field.

Working with fields that contain encrypted data

  • Encryption converts the data in a field to text. Therefore, these fields can be searched for data using only the following operators: IsIs NotIs Empty, and Is Not Empty. This applies to both reports and workflows.
  • In reports, the fields containing encrypted data will display the original (decrypted) value by default. This can be customized as follows:
    • Set the Display Value as:
      • Without mask: Displays the decrypted value. This is selected by default.
      • Show first n characters decrypted, while the rest of the data being represented by a few asterisks (*)
      • Show last n characters decrypted, while the rest of the data being represented by a few asterisks (*)
      • With mask: Mask the data by displaying five asterisks (*) instead
    • Enable Show value on click (or tap): This option becomes available when the Display Value is set with a value other than Without mask
